Patented May 19, 1931 JAMES M. NAHON, OF MADRID, SPAIN NONSKID DEVICE FOR BOOTS AND SHOES Application filed August 1, 1930, Serial No. 472,248, and in Spain January 17, 1930.

The present invention is an improvement over my invention forming the subject matter of my co-pending application Serial No. 273,115, filed April 26, 1928, and comprises a new device for fitting non-slip or anti-skid chains to boots-and shoes.

In devices hitherto known for fixing the actual non-slip member to the boot or shoe, the disadvantage is present in that another fixed or removable member is required, which is applied to the surface or side of the boot or shoe. This may cause discomfort to the foot of the wearer or cause one foot to strike against the other, whereby the V boot orshoe suffers in appearance and may even become damaged. Such systems also do not provide the necessary rigidity or secure fastening to the foot, and they move from place to place when the person walks. It also happens that the chain, which, in

order to be absolutely effective, should be taut or under tension, which can only take place in a limited number of positions, if

at all; and, when loose, it is attended by the following disadvantages among others:

The device becomes decentralized, whereby the non-slip effect is lost; a noise is produced when walking; and the foot may catch in any obstacle.

Finally, the chain often forms an obstacle and a source of discomfort beneath the sole of the shoe if the sole is not made of rubber or some other soft material when walking over hard surfaces, such as ice.

The present invention overcomes the disadvantages and defects pointed out in the foregoing and consists essentially in the arrangement of a number of supporting or securing members securely fixed between the sole of the shoe and the upper part there:

of or on the upper border of the sole itself. The supporting members may also be secured under the sole of the shoe, as, for example, in the arch part of the shoe near The supporting members are adapted to secure one or more rows of chains, which are suitably arranged under the sole and also the heel, if desired. The supporting or securing members may, of course, be hidden so that when the non-skid or non-slip device is not in use it cannot be detected that the shoe is fitted with means whereby chains may be secured to the sole of the shoe; also, the supporting members are so provided that the chains may be fitted or removed in a very short time by means of suitable clasps or hooks.

The nonslip or skid chains are maintained under tension when provided on the sole of a shoe by means of one or more springs of any suitable type and also any discomfort to the foot from the chain may be rectified by interposing therebetwcen and the sole a strip of any soft material, preferably rubber.

It is a further object of the present invention to provide a cross-brace arranged between the inner sole and the outer sole of the shoe, which is adapted to interconnect the supporting members arranged on opposite sides of the shoe. This further strengthens and secures the supporting members to the shoe and also adds to the strength of the sole of the shoe by rendering it more rigid. The cross-brace also prevents, to a certain extent, any tendency of the sole to become deformed due to expansion or from any other cause which can readily happen with crepe rubber or other soles.

Further objects will be apparent from the following description taken in connection with the accompanying drawings in which like characters indicate corresponding parts throughout and in which:

Figure l is a perspective view of a shoe showing the bottom thereof and a portion of the sole pulled away to show the supporting members and the cross-brace,

Fig.2 is a bottom view of the shoe of Fig. 1 with the non-skid chains fastened in' place,

Fig. 3 is a side view of the securing clasp in open position, i

Fig. 4c is a top view showing the chains of Fig. 2 in a specific arrangement,

Fig. 5 is a side View of the shoe showing the supporting members, and

Fig. 6 is a side View similar to Fig. 5 but showing the chains secured to the supporting members.

In apreferredconstruction of the present invention, as clearly shown in Fig. 1, a pair of supporting or securing members a, preferably made'of metal, are secured to the inner sole of the shoeso that the ends thereof project a trifle as indicated in Figs. and

, together and thereby strengthens thein ancl; also the shoe itself in order toform-a rigid construction. It, is,-'of course, possible to;

.6. These supporting membersare provided witha brace b,-whi'ch isprovided entirely within the construction of the shoe and. it, therefore, isinvisible from the outside. The brace interconnects the supporting members secure these'members in the shoe even after it has been completed, but it is preferable to supply them in the shoeat the time that It is manufactured.

The chains may be'arranged in lany suitable manner and any number can be utilized "asmay be desired, but for all practical purposes the construction shown in Fig. 2" has been found to-be most adaptable for almost all conditions. Therchain consists of three are secured f each by means of one end to, a 'supporting-niember by means of link- 6 shown in Fig.- 6.- The two chains are consections, of which the lateral sections e nect'ed? together at the other endsby a clasp 05 arranged approximately in the center of thesole o'n-the bottom thereof, which acts at the same time as a spring and serves to impart to the chain the required'elasticity and flexibility in different directions, as well as tokeep' it under tension. This clasp also serves as a securing means for-"the longitudinal chain 9 which is'connected at one end thereto and the otherend to a suitable ring fastening f secured to'the bottom of the sole in the instep. This chain 9 and chains 0 provide" a' T-shaped construction and is a-more secure device than if only the l ateral chains were {used. Also, the chains 6 can be shaped tof'orm a Tby making them a triflewlonger and the chain g-somewhat shorteror any other suitable shape'can 'beadopted, but, it has been found thatthe arrangement as 'disclosed in Fig. Q giveS the bestresults and is more comfortable to the wearer.

If the sole of the shoe is made of a hard material, such as leather, a strip of; soft material, as rubber, can be inserted between the "chains and the sole, which will thus act as a shock absorber and prevent undue discomfort to the foot of the wearer.

-- The chains can be fastened as, for incoin-pri-singa plurality of supporting or securing members fastened'to-the inner sole of the shoe; and a chain adaptedto be removt R ably attached to the supporting members over the sole of the shoe.
